Description
Technical field
The present invention relates to a kind of heat radiation module, especially a kind of multiple heat dissipation module.
Background technology
Along with improving constantly of electronic installation usefulness, heat abstractor or system have become one of outfit indispensable in the existing electronic installation, because if the heat energy that electronic installation produced is not in addition suitably dissipation, gently then usefulness lowers, and is heavy then can cause burning of electronic installation.Therefore, can produce the surface or the side of the electronic installation (for example central processing unit) of high heat usually can be with a heat abstractor with its heat energy that is produced of dissipation.
A kind of known heat abstractor 10 has a fan 50 and a radiator 60 as shown in Figure 1a.And this fan 50 is fixed on the upper surface of radiator 60, and the lower surface of this radiator 60 is attached on the desire heat abstractor (not showing, for example a central processing unit).The shortcoming of this known heat abstractor 10 comprises at least: (1) radiating effect is not inconsistent demand; (2) do not have standby (redundant) function, details are as follows respectively for its reason.
See also Fig. 1 a, this known heat abstractor 10 only has single fan 50, so when this fan 50 breaks down, this known heat abstractor 10 will burn because of dissipation heat energy rapidly causes desiring heat abstractor.
Because the raising of electronic apparatus functions, only can't satisfy the requirement of electronic installation that function increases day by day to radiating efficiency only according to a fan.So known technology proposes to increase with two fan 50a that pile up and 50b the design of radiating efficiency.Shown in Fig. 1 b, known technology has standby functions for making heat abstractor 10, increases another extra fan 50b on fan 50a, yet, so understand, and make integral body can't reach the radiating effect of expection, and increase noise because of the phase mutual interference between two fans.Or shown in Fig. 1 c, known technology uses a bigger fan 50c, yet this measure but can't take into account radiating effect and standby functions.
Therefore, in this technical field, need a kind of heat abstractor of novelty badly to address the above problem.
Summary of the invention
The objective of the invention is to propose a kind of multiple heat dissipation module to take into account radiating effect and standby functions.
Multiple heat dissipation module of the present invention comprises a radiator and a fan module.Wherein this radiator has a plurality of heat conduction fins.This fan module is formed on the radiator, and has one first fan and one second fan.This framework comprises a pedestal, an outer wall and a plurality of rib.Wherein, this pedestal has one first central siphon and one second central siphon that extends in the opposite direction.This first central siphon is coupled in above-mentioned first fan, and this second central siphon is coupled in above-mentioned second fan.This first fan and above-mentioned second fan by outer wall institute around.These a plurality of ribs by base extension to housing.
In the present invention first fan and second fan can be mutually in response to each other fault and improve rotating speed.Make first fan of the present invention and second fan have the relation of mutual interlock.This first fan has more a first control circuit and one first signal output end, and above-mentioned second fan has more a second control circuit and one second signal output end.Wherein this first signal output end is coupled in this second control circuit; This second signal output end is coupled in this first control circuit.Whether normally the signal that this first signal output end and this second signal output end are exported represents rotating speed signal.For example work as rotating speed just often, this signal is a logical one, and when rotating speed was unusual, this signal was a logical zero.But work as rotating speed just often, this signal also can be logical zero, and when rotating speed was unusual, this signal was a logical one.
When first fan and second fan all just often, first fan and second fan all can turn round with the slow-speed of revolution.Yet when a fan failure was wherein arranged, another fan will improve rotating speed.For example, when first fan failure, this second control circuit can improve the rotating speed of second fan according to the signal that first signal output end is exported, and uses the heat-sinking capability that compensation is lost.For reaching this purpose, first fan and second fan at least must a high rotating speed or slow-speed of revolution runnings, are necessary for a pair of rotating speed fan at least.
In addition, for reducing noise and promoting radiating efficiency, the switched in opposite of first fan and second fan.So, can offset the wind speed of tangential direction, and make axial air quantity more concentrated.
Multiple heat dissipation module of the present invention can also be for comprising a radiator, one first fan, one second fan and a support.Wherein, this radiator has a plurality of heat conduction fins and by the defined groove of this heat conduction fin.This first fan and second fan are to pile up or series system is formed in this groove and is embedded in this radiator.
This support has more a pedestal, a housing and a plurality of rib.Have one first central siphon and one second central siphon that extend in the opposite direction on this pedestal.This first central siphon is coupled in above-mentioned first fan, and this second central siphon is coupled in above-mentioned second fan.These a plurality of ribs by base extension to housing.
First fan in the said structure of the present invention and second fan also can be mutually in response to each other fault and improve rotating speed.
Characteristics of the present invention and advantage be, simple in structure, noise is low, radiating efficiency is high, and when a fan broke down, another fan will improve rotating speed, thereby had increased standby functions.
